Hi all,
I had a saddlebag mounting bracket break loose and punch a hole in the reservoir chamber of my FastAce shock on my 2014 model S. No more gas pressure, and dampening obviously doesn't work much anymore.
As a temporary measure I tried out the Wotefusi shock listed in the aftermarket options in the Unofficial Manual, but it is completely unusable as is -- weak spring, almost no dampening, not really adjustable, and it bottoms out riding over the slightest bump in the road (and I'm a skinny guy).
So I need to rebuild my FastAce shock. I can't find any replacement parts for the FastAce shock, so I will try to repair the reservoir chamber and see if I can get it to hold pressure.
Does anyone have specifications for the weight/type/volume of oil for the stock FastAce shock?
Or the Nitrogen pressure that it uses by default?
Google has failed me.
The needle-type gas fill port annoys me, so I will probably change that to Shrader as well while I'm at it.

That certainly isn't anything that I would tackle. I have no idea about the FastAce shock, but most other pressurized shocks seem to require nitrogen at 300 or 400 psi pressure, I believe. I am not sure how you would repair a shock's reservoir to deal with that kind of pressure. It might be possible to buy a new FastAce shock somewhere. Are they still in business and do they have a distributor in your country?

I replaced the Fastace rear shock on my 2013 S with a Wilbers. They can be bought from EPM Wilbers in New Jersey or Ted Porters Beemershop in California, just down the road from the Zero factory. I have used Wilbers shocks on my Beemers for years The Wilbers replacement is longer than the stock Fastace so the bike sits higher and needs a longer kickstand (available from Zero) but it vastly improves the bike's handling and the craftsmanship of the shock is spectacular.

Jon, is that the Wilber’s 640? I’m thinking about the replacement and couldn’t find much of a written review. Apart from the taller ride height, what else do you think about it? Is the rebound adjustments enough?

I am broke these days and I am trying to save money, so a $600 Wilbers shock would be a nice upgrade when my budget allows that. Currently the stock BDA58RC Fastace shock is listed at $350 new.
I don't mind working with high-pressure systems if the repair is possible. I am also looking for anyone with a broken/used FastAce shock that I could use for parts instead of having to rebuild the chamber.
I have contacted FastAce, but they have not responded to me.
